You can be sure all the same data for US publishers is being collected and uploaded into this system as they do not even need consent authorizations. This will prevent them losing track of inactive publishers (faders) that cause them problems down the line so that judicial action can be meted out.
In countries where this Consent is now required, I assume it has been difficult to stay under the radar if you refuse to sign. There is NO WAY I would willingly give consent to anything like this.
